Calibration Test Sites Selection and Characterization

The scope of the project is to select, identify and characterise reference test sites that will be used for the calibration and characterisation of different sensor types. The study is part of the ESA strategy for ensuring the quality (calibration, validation and operational quality) of data developed for current and future missions within the Explorers and GMES framework. The output of the project can be found in the table below.

This document describes a classification of sensors based on the needs of external calibration in terms of radiometry, geometry, spectral, and image quality. Three classes are reviewed: Low spatial resolution optical sensors, High spatial resolution optical sensors, atmospheric sensors.
